Description
Technical field
The invention belongs to building structure technology field, it is related to a kind of architectural engineering and combining structure.
Background technology
As being continuously increased for China's steel yield is perfect with continuing to develop for long strands, steel construction has been obtained rapidly
Development, industry and civil buildings in applications it is more and more, newly constructed the factory buildings and large span venue at some, more also change
In making the enlarging of project and adding layer to construct, there is the connection of increasing steel construction and concrete structure, such as concrete column
The connection of the connection, girder steel and concrete column of connection, steel column and beams of concrete with steel column, these connections pass through chemical anchors mostly
Bolt or expansion bolt are connected.
Wherein, the connected mode of traditional girder steel and concrete column is portal-rigid frames (Fig. 1) or bent structure (Fig. 2), but
Both modes, it is not ideal at aspects such as speed of application, cost, thermal-insulating waterproof effect and compressive properties;Therefore in recent years, it is long
The more single storey industry workshop in tessellated region uses the structure type of reinforced concrete pile herringbone girder steel, due to this structure both not gate
Formula rigid frame (Fig. 1), and unconventional bent structure (Fig. 2), on the one hand, the connecting node of existing reinforced concrete pile herringbone girder steel
Processing mode be girder steel one end with it is concrete column articulated, the other end is slide hinged with post, but this kind of method is cumbersome, and construction is multiple
It is miscellaneous;On the other hand, although the structure of this reinforced concrete pile herringbone girder steel takes full advantage of the compressive property and steel of concrete column
The anti-bending strength of beam, but the regulation of respective standard is made in calculating and construction of the national regulation not yet to this node, does not also have
Ready-made specification or the maps and census records of the border regions can be quoted directly.
The content of the invention
It is of the invention vertical the present invention solves the technical problem of the connecting joint structure for providing a kind of column and girder steel
The stress performance of the column of post and steel beam connecting joint similar to framed bent, but girder steel stress performance similar to arch, there is level
Power, thus stress performance is slightly different with framed bent, the connecting node stress of present invention design is clearly, workable, big
Applied in amount engineering, in practice it has proved that its is safe and reliable, and similar item can be used for reference, and is particularly well-suited to the column of single storey industry workshop
With the connecting joint structure of girder steel.
In order to solve the above technical problems, one aspect of the present invention is:
The connecting joint structure of a kind of column and girder steel, including column and the girder steel being fixed on above the column are provided,
The bottom surface of the end of the girder steel is plane, and the end of girder steel has leading flank and trailing flank, also including crab-bolt, steel plate, angle
Steel and nut, the crab-bolt is at least provided with four, and nut quantity is identical with crab-bolt quantity, and the angle steel is at least provided with two;
Imbed the top of the column in the lower end of the crab-bolt;
The middle part of the lower surface of the steel plate has a channel-section steel, and the steel plate and its channel-section steel imbed the upper of the column
End;
The bottom surface that the steel plate has through hole corresponding with the crab-bolt, the end of the girder steel has and the crab-bolt pair
The perforate answered, the upper end of the crab-bolt passes through the perforate of the through hole and the girder steel of the steel plate, and by corresponding with crab-bolt
Nut is twisted the steel plate and the girder steel are connected in crab-bolt;
Each described angle steel is made up of orthogonal side plate and base plate, a base plate for the angle steel and the steel plate
Upper surface is welded and the leading flank of side plate and the girder steel is welded, the upper surface of the base plate of another angle steel and the steel plate
Weld and side plate is welded with the trailing flank of the girder steel;

The wall thickness of channel-section steel is 10mm.
Further say, the size of the upper surface of the column more than the steel plate size, the steel plate it is front and rear away from
From the longitudinal separation of the end more than the girder steel.
Further say, the girder steel behaviour font girder steel, the column is armored concrete concrete post.
Further say, also including purlin, the purlin is fixed between the girder steel and roof color steel.
Further say, the perforate of the girder steel is the slotted hole of Φ 25.5mm × 50mm.
Further say, the crab-bolt is provided with four, and the angle steel is provided with two.
Present invention also offers a kind of described column and the construction method of the connecting joint structure of girder steel, according to following steps
Suddenly carry out:
S1. pouring reinforcement concrete concrete post, while pre-buried four crab-bolts, pre-hardening 2-8h;

The beneficial effects of the invention are as follows:
The bottom surface of girder steel the firstth, of the invention offers slotted hole, mainly easy for installation, girder steel before being twisted eventually due to crab-bolt
And steel plate etc. has horizontal stretch deformation under Gravitative Loads, this aspect can be such that the horizontal thrust of column top reduces, opposition
Post is favourable;On the other hand girder steel mid span moment and amount of deflection can be made to increase;Because this horizontal force is smaller, thus it is this influence also compared with
It is small, amount of deflection can be solved the problems, such as by arch camber during design girder steel, and intensity surplus meets requirement;
Secondth, the horizontal force between column and girder steel is transmitted by the frictional force between girder steel and column, if the friction
Power not enough, then must set shear key, because crab-bolt can not transmit horizontal force, and because steel beam bottom of the invention offers length
Circular hole, can reduce column top horizontal thrust, i.e., frictional force reduces, it is not necessary to sets shear key, can just meet design requirement, applies
Work is relatively easy, and the duration is relatively short, easily realizes;
Angle steel is welded between 3rd, the steel plate of column top of the invention and girder steel, for transmitting the level at node
Power and shearing force, strengthen the intensity of node and the anti-bending strength of girder steel;
Connected mode between 4th, column of the invention and girder steel is easily real when causing using software modelings such as PKPM
It is existing, each parameter can be precalculated, it is ensured that the accuracy of design and the safety and stability of engineering;
5th, the speed of application of reinforced concrete pile of the invention and herringbone steel beam connecting joint is fast, and cost is small, is incubated, prevents
Preferably, application is more and more extensive at present for water effect;
6th, the bottom of the steel plate of connecting node of the invention has a channel-section steel, can transmit between girder steel and column
Shearing, strengthens the weight capacity of girder steel and the anti-bending strength of girder steel;
The stress performance of the column of column of the invention and steel beam connecting joint similar to framed bent, but girder steel stress performance
Similar to arch, there is horizontal force, thus stress performance is slightly different with framed bent, beam-column connection way currently there are no ready-made
Specification or the maps and census records of the border regions, the present invention design connecting node stress clearly, it is workable, applied in a large amount of engineerings, put into practice
Prove that its is safe and reliable, similar item can be used for reference.
